Begonia plant named &#39;Nadine&#39;

ABSTRACT

A new and distinct begonia plant with yellow-orange colored double flowers.

BACKGROUND OF THE INVENTION

[0001] The present invention comprises a new and distinct cultivar of Begonia Elatior known by the varietal name ‘Nadine’. The new variety was discovered in a planned breeding program as a single plant in a group of plants of the parent cultivar in Amstelveen, Netherlands, in 1998. The new variety is a mutation of ‘Britt’ (unpatented). The new variety differs from its parent through its yellow/pale yellow flower color and a similar variety, ‘Rhianne’ (unpatented) in its flower color and peduncle color as follows: Rhianne Nadine Middle of lower side, Orange Group 25D Yellow-Orange Group 18B outer tepal Middle of lower side, Orange Group 24D Yellow-Orange Group 21D inner tepal Peduncle Reddish Greenish

[0002] The new variety was first asexually reproduced by cuttings in Aalsmeer in February of 1998. The new variety has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive propagations.

[0003] The new variety, when grown in a glass greenhouse has a response time for rooting from a terminal cutting of 14 days.

DESCRIPTION OF THE DRAWING

[0004] The accompanying photographic drawing illustrates the new variety, with the color being as nearly true as is possible with color illustrations of this type.

DESCRIPTION OF THE PLANT

[0005] The following detailed description sets forth the characteristics of the new cultivar. The data which defines these characteristics were collected by asexual reproductions by cuttings in a controlled greenhouse environment. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London.
